Conan Edogawa, once Shinichi Kudo, a 17-year-old prodigy detective renowned for unraveling intricate cases, survives an experimental drug meant to kill him after witnessing a criminal exchange. The poison de-ages his body to that of a seven-year-old, compelling him to adopt the alias "Conan Edogawa"—drawing inspiration from mystery authors Edogawa Ranpo and Arthur Conan Doyle—to shield loved ones from the shadowy organization responsible. He takes refuge with Ran Mouri and her father, Kogoro Mouri, a bumbling private detective, posing as their distant relative.
Retaining his sharp intellect, Conan covertly solves Kogoro’s cases using gadgets like a voice-changing bowtie and tranquilizer watch, masking his involvement to preserve Kogoro’s reputation. Enrolled in elementary school, he forms the Detective Boys with classmates Ayumi, Mitsuhiko, and Genta, balancing youthful antics with covert investigations. Though he mimics childlike naivety around adults, his deductive slips are hastily attributed to TV shows or mentors.
During the *Sekigan no Flashback* incident, Conan partners with Nagano Inspector Kansuke Yamato—a survivor of an avalanche and gunshot wound—and Public Security agent Rei Furuya to expose a conspiracy rooted in a past robbery. He deduces undercover agent Atsunobu Hayashi’s vengeful motives, linked to his lover’s death, and thwarts an avalanche attack. Utilizing a radio observatory to intercept satellite data, Conan’s resourcefulness shines in averting disaster.
His perceptive grasp of human dynamics emerges when he subtly informs officer Yui Uehara of Yamato’s survival to alleviate her anguish. Trusted allies like FBI agent Jodie Starling and Inspector Yamato sense his exceptional talents, yet his true identity remains closely guarded. Juggling perilous investigations with school life, Conan maintains fragile normalcy through friendships and classroom routines.
His dual existence intertwines childlike camaraderie with grave responsibility, mediating the Detective Boys’ escapades while confronting threats tied to his past. His evolving bond with Ran, who unknowingly confides her longing for Shinichi, layers emotional tension. Striving to reclaim his original life and protect others, Conan embodies a paradox—youthful guise cloaking a detective’s relentless resolve, forever navigating the razor’s edge between secrecy and truth.
